Application filed January 9, 1918.

To all w 7mm it may concern Be it known that I, THOMAS OLINGER, a citizen of the United states of America, residing at Holland, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Surgical. Operating-Tables; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to surgical operating tables and is more particularly concerned with tables adapted for use in examining and operating upon small animals. It is an object and purpose of the present invention to provide a table of this character having many new and useful features of construction relating to the adjustment thereof, and to appliances to be used in conjunction with the table all of which will appear fully and in detail in the following description taken in conjunction with the accompanying drawings which show a preferred and practical embodiment of the invention;

In the drawings, Figure 1 is a side elevation of the table. Fig. 2 is a similar side elevation, but taken from the opposite side, the lower part of the supporting standard being omitted.

I Fig. 3 is an end view of the table.

Fig. 4 is a fragmentary vertical section through the supporting post or standard and illustrating the method of angularly adjusting the table and holding it in any position to which it may be adjusted, and

Fig. 5 is an enlarged horizontal section taken substantially on the line 55 of Fig. 2.

Like reference characters refer to like parts in the several views of the drawings.

In construction, a hollow supportlng-post 1-is provided which is carried by a plurality of diverging legs 2 at its lower end, the upper end thereof being divided to form two spaced apart substantially vertical arms 3, between which a relatively heavy head or bar 4 is rotatably mounted midway between its ends,turning about the bolt 5 as its pivot. A semi-circular sector 6 is cast integral with the head 4, depending therefrom and passing between the arms 3 heretofore described, its outer edge being provided with a plurality of spaced apart notches 7. A locking lever 8 is pivotally mounted on the post 1 Specification of Letters Patent.

Serial No. 210,976.

between said members 3 and below the sector 6, it having an upwardly projecting lug adapted to seat in any one of the notches 7. Normally the lever 8 is moved toward sector 6 by a spring 10. Rod 11 is connected to the lever 8 extending downwardly through the post 1 and having connection at its lower end to a foot lever 12, pivotally mounted at one end on one of the legs 2, whereby by pressing with the foot on the free end of the lever, a disengagement ofthe lug 9 from any of the notches 7 may be effected to permit a; tilting of the head 4 to any desired position after which, by reengagement of the locking lever 8 with said sector 6, the head and the attached mechanism carried thereby is held against movement.

At each end of the bar or head 4 upper and lower guide lugs 13 and 14 extend outhand wheel 19 fixed thereon. It is apparent that by rotation of either hand wheel the rods 15 may be raised or lowered in unison.

At the upper end of each rod 15 a head 20 is secured which is provided with two diverging upwardly extending arms 21, above the upper ends of which, table members 22 lie, each being connected to transverse bars 23 lying on the under side thereof. The inner ends of the bars 23 have pivotal connection with the upper ends of the arms 21, while supporting arms 24 likewise have pivotal connection at their upper ends to the bars 23 at a point between their ends, the lower ends of said arms 24 being pivotally connected to lateral extensions 25 formed at scribed and leave a slot the full length of the table. It is apparent that with the vertical movement of rods 15 the inner edges of the table members are raised and lowered, while the outer edges remain substantially at rest or at least have but slight movement,

whereby the members 22 may be located at various angles with respect to each other, but at all times leaving the slot between the inner edges of full width for the full length of the table.

A pin 27 is mounted adjacent one end of the head i and passes through a lateral extension 25 thereof to seat in any one of a number of openings 28 made in the face of one of the combined gear and hand wheel members attached at the end of the shaft 18, as shown in Fig. 5. At its other end the pin 27 passes through and has a support in a bracket 29 permanently secured to and projecting laterally from the bar a. A coil spring 30 is secured atone end to the pin 27 and is disposed between the same and the bracket 29. This spring under compression has a tendency to move the pin to enter the recesses 28, as will be obvious. One side of the bracket 29 is cut at an incline as indicated at 31, and the free end of the pin 27 is bent at right angles to form a handle 32 adapted to ride against this incline whereby on turning the handle sufliciently, pin 27 is disengaged from the opening 28 in which .it may be inserted, thereby freeing the shaft 18 for rotation, upon which the table members 22 maybe adjusted to any desired position and held therein on release of the looking pin 27 Each table member 22 at its outer edge is bent upwardly for a short distance and then at right angles substantially to the plane of the main portion of the table member, as indicated at 33, forming a relatively wide side in which a plurality of spaced apart bayonet slots 34: may be cut to detachably receive members 35 to which hopple ropes 36 may be connected as shown in Fig. 2,

thus providing simple and easily adjusted hopples at each side of the table.

drain trough 37 oi substantially channel shaped formation, is slidably received between the arms 21 directly underneath the longitudinal slot in the table. In practice a staple 38 depends from the trough and is adapted to receive the end of a hook 39 mounted at 40 on one of the heads 20 heretofore described. The trough is readily removed on disconnection of the hook for cleaning and is held against movement by the hook. This trough, as is obvious, is of utility to carry away any fluid that may come to the same through the slot between the two members of the table.

By operating either hand wheel 19, the table members 22 may be adjusted so as to form V-shaped troughs, the angles of which may be varied at will, or they may be moved so as to lie in a common horizontal plane. The table as a whole may be turned about the pivot 5 to any desired cngle and all of the adjustments noted are particularly simple and effective. When an animal is placed on the table, it can be secured through use of the hopples or by straps or cords connected thereto as the occasion may require, and by the various adjustments noted, the table may be turned to bring the animal in any convenient position for examination or for operating upon the same.

I claim:

1. An operating table comprising a sup port, a head adjustably mounted thereon, vertical rods slidably mounted in spaced apart relation on the head, means for raising or lowering said rods, table members pivotally connected at their adjacent edges to the upper ends of said rods, and arms pivotally mounted at their lower ends on said head and pivotally connected at their upper ends to said table members.

2. An operating table comprising a supporting head, spaced apart vertical rods slidably mounted on the head, means for raising or lowering said rods, a head having two upwardly extending spaced apart arms connected to the upper end of each rod, two table members pivotally connected adjacent their inner edges to said arms thereby providing an open slot for the full length of the table, and arms pivotally connected at their lower ends to said-supporting head and at their upper ends to the table members at points between the sides thereof, substantially as described.
